Abstract

This research examines how communicating effect sizes in nontraditional ways (i.e. more common language presentation) versus traditional ways (i.e. statistics) affects comprehension of information. Effect size results were presented in either a traditional or nontraditional format and four types of comprehension were measured to determine if format had a significant impact on comprehension. Results showed that effect size display format was associated with two types of comprehension (instrumental/relationship comprehension and components comprehension) but not the other types examined here. Implications for current practice and future research are discussed.
